I read an article about agnosia and how it affects people's perception of the world.

That sounds interesting! What exactly does it mean?

Root Explanation

Agnosia → It is formed from "a-" (meaning without) and "gnosis" (from Greek "gnōsis", meaning knowledge). The word "agnosia" refers to a condition where a person lacks knowledge or awareness about certain stimuli, despite having intact sensory functions.

Memory Tip

Think of 'without knowledge' — 'a-' means without, and 'gnosis' means knowledge. This helps you remember that agnosia is a condition where someone lacks knowledge about certain things.
